Lol... I know that but I was trying to get a consensus by consulting many sources...

so what do you think... I have an acc wire (red) a voltage regulator wire black with a blue band on it... and a wire that is connected to the same post as my postive cable on the solenoid or starter motor... which ones should be paired in your opinion on which posts?

I can`t understand what you are asking for here. They should be connected just like shown in the wiring diagram.

Have you looked at the wiring diagram in the link that I posted?

It shows the wire from voltage regulator connected directly at the positive battery post.

Is that a 93 wiring diagram for this model?

First of all thank you for that.

I will have to spend some time seriously looking it through. I can see what you mean about the regulator straight to the battery and the copper side vs the silver side.

Where do you get these diagrams? I looked up an actual 93 service manual but couldnt find a physical copy.

Im really curious why when comparing the start and stop relay the ground is reversed from 86 yo 85... all relays are the same so why aren't all sockets wired the same... more curiosity than function need

Don`t worry about terminals 85 and 85 being reversed, unless the relay is diode protected (in that case 85 should be ground).

I posted the link for the Diagnostics Manual and Wiring Diagram in post #38....

Spend some time looking at it...

The layout of the clymer diagrams are not great, a lot of them are incorrect.

Here is the real deal:

Harley Davidson Service Information Portal
Thanks! I'm registered on that site now. Well worth it.

I feel like somehow I'm missing links and attachments when I read your posts initially. Maybe its when I read them from the email notifications.

I've asked a couple times earlier but maybe the posts were too busy to pick out the question.

What might have happened when I plugged this


Which was Attached to my battery... into this...


Also attached to my battery...

It popped and smoked...

My surprise and recoil ripped the alligator clips right off..

What did I potentially do?

I just want to make sure I didnt cause another major problem that couldn't have been caused another way and therefore be very difficult to find.

Remember... next time I started bike.... this happened...

Thats on the negative side.

The battery post melted because of a poor connection, most likely it was loose.

If you connected both of those units via the sae plug, then you crossed your battery connections (shorting the positive directly to the negative), it would have just blown the little fuse.

The reason I was using alligator clips is because it wouldn't take a charge via pigtail... I assumed fust was broken without even looking... Im so comfortable doing this and yet not used to having two connectors in such close proximity that you could ever plug into the wrong one. If fuse was already blown shouldn't it have done nothing?

I'm trying to print that wiring diagram.... I want to print it huge at staples. Id like to color it and draw arrows representing current flow. Current flow arrows would make these so much easier to understand.
